Toxic components leaching from tire rubber

Article

Tire rubber is a complex mixture of a variety of chemicals, e.g., rubber polymers, carbon blacks, silicas, process and extender oils, vulcanization chemicals, and chemical antidegradents (Barbin and Rodgers, 1994). Leachates of tire rubber are toxic to a range of aquatic organisms; see for example the review by Evans (1997). Attempts made so far to identify the components causing the toxicity of rubber leachates have focused on chemical fractionation and characterization followed by toxicity testing of different fractions. Toxicity identification evaluations of leachates from tire plugs leached in deionized water have indicated that zinc was the main cause of toxicity to Ceriodaphnia dubia (Nelson et al., 1994). Microtox toxicity was caused by several organic compounds spread through a range of polarities (Anthony et al., 1995). A toxicity identification evaluation on leachates obtained from tire wear material leached in reconstituted water (pH 8, hardness 250 mg/L as CaC03),...
